Show HN: Open-Source Framework for Real-Time AI Video Avatars

Hi, I’m Sagar. We just open-sourced a framework to build real-time AI-powered video avatars you can drop into any app or website.

You can use it to create sales assistants, customer success agents, mock interviewers, language coaches, or even historical characters. It’s modular (choose your STT, LLM, and TTS provider), production-ready, and optimized for ultra-low latency video generation.

Features:

- Real-time speech-to-video avatars (<300ms)

- Native turn detection, VAD, and noise suppression

- Modular pipelines for STT, LLM, TTS, and avatars with real-time model switching

- Built-in RAG + memory for grounding and hallucination resistance

- SDKs for web, mobile, Unity, IoT, and telephony — no glue code needed

- Agent Cloud for infinite scaling with one-click deployments — or self-host with full control

Would love feedback from anyone working with video, avatars, or real-time conversational AI!
